5 axis CNC Bridge Saw BK2020 5+V

5 axis CNC Bridge Saw BK2020 5+V
This bridge saw has everything a technologically advanced bridge saw needs to have today: 5 interpolated axis, spindle with half inch fitting with trough-spindle lubrication, tilting table up to 85°, vacuum system for parts movement during automatic cut process, on-board camera, blade and stone thickness probe (optional).

Relationship between the slab size and overall size of the machine
The first evident advantage is the ratio between working area and overall machine dimensions.
This machine with a working area of 4000mm x 2420mm occupies only 15.5 square meters, making it possible to fit two machines in the space of a traditional bridge saw.

Easy unload of parts from the table
The table has three sides that are always accessible to the operator, who can then unload parts more easily and more safely.

Increased rigidity of the machine
The guides of the bridge are anchored to the ground and thus provide a better rigidity to the whole machine.

Bridge resistance to twisting
5-axis bridge saws are exposed to always-changing twist forces, because the blade cutting direction is not always parallel to the bridge.
The shorter bridge solidly anchored, not on wheels or rollers, has greatly improved twist resistance.

Improved Z axis rigidity
An improved motor tilting system combined with a correctly sized blade allowed us to lower the bridge and to shorten the Z slide.
The shorter Z frontally mounted on the bridge has increased rigidity but kept the same working height capacity.

Lower water consumption
The traditional cooling system expects huge quantity of water to cool 30% of the blade perimeter, or only the contact side, this cover (patent n° 3684608) keeps the blade submerged in water for 70% of the perimeter.
Cooling trough submersion needs less water and almost totally eliminate water splashes.

Rapid movements
The smaller size of the machine allows it to reach a point before compared to a larger machine.

Blade motor with vector technology
A vector motor and an induction motor have different performance.
With the same consumption (kW) the vector motor has twice the torque (Nm).
Vector motor technology allows the motor to keep a constant torque up to 6000 rpm, instead with an induction motor, even if controlled by VFD, as the speed increases it loses torque, but the consumption increases.
Using vector motor technology allowed us to increase performance, and drastically reduce consumption and the dimensions of the blade motor.

Increased cutting depth
The motor and flange diameter of only 160mm allows cutting 100mm thick stone with a blade of only 360mm diameter.
With a traditional motor you would instead need a 450mm blade to cut the same thickness.

Better cutting performance
A small blade because it’s thinner reduces sludge left from the cutting process, also because it’s cutting less it can cut faster, and it leaves shorter overcuts. Another advantage of a small blade is that it requires less water and less power to run.

Machine installation
Machine’s mono-block structure allows installation in less than a full working day on a flat concrete floor, without needing to spend more to build walls or special foundations.

The machine is supplied with a program that allows work in manual.
It’s included with the machine a CAD/CAM program (installed on a windows PC made available by the customer), with functions to import slab pictures, automatic cutting process and movement of parts with the vacuum.
